The Mozilla Foundation regularly leads or joins in political action relevant to its mission. For example we campaigned against SOPA/PIPA and CISPA [1], submitted a Net Neutrality proposal to the U.S. FCC [2], and have testified multiple times to the Librarian of Congress and elsewhere in favor of DMCA exemptions and DMCA reform [3].
